Description

Die Erfindung bezieht sich aufei,nenFlüssigkeitsstoßdämpfer, insbesondere für Kraftfahrzeuge, bei dem ein 'hin und her schwingender Nocken zwischen einem einteiligen Doppelkolben angeordnet ist, dessen zugehörige Arbeitskammern durchventilgesteuerte Kanäle miteinander in Verbindung stehen. Ein derartiger Stoßdämpfer arbeitet nur geräuschlos, wenn Spiel zwischen Kolben und Nocken nicht auftritt, und zwar Spiel sowohl in der Schwingungsebene,dies Kolbens als auch senkrecht dazu. Das Spiel in der Schwingungsebene wird durch unvermeidliche Einbautoleranzen des Kolbens, des Nockens und der Pilze sowie :durch Abnutzung der Angriffsflächen des Nockens an den Kolben verursacht. Es konnte bisher nur durch abgefederte Kolbenpilze ausgeglichen werden.The invention relates to liquid shock absorbers, in particular for motor vehicles, in which a 'reciprocating cam between a one-piece double piston is arranged, the associated working chambers by valve-controlled Channels are in communication with each other. Such a shock absorber only works Noiseless if there is no play between the piston and the cam, namely play both in the plane of oscillation, this piston, as well as perpendicular to it. The game in the oscillation plane is caused by unavoidable installation tolerances of the piston, the Cam and mushrooms as well as: by wear of the contact surfaces of the cam caused the piston. So far it could only be compensated by cushioned piston mushrooms will.

Alle bekanntgewordenen. Federanordnungen sind aber nicht ausreichend, um die großen hydraulischen Arbeitsdrücke auf die Dauer auszuhalten. Die geringsten Erm üdlu.ngserscheinungen der Federn genügen bereits, um Klopfgeräusche auftreten zu lassen. DieUnterbringung genügend kräftiger Federn i!st im allgemeinen nur eine Raumfrage. Sie bietet bei der Teilung des Doppelkolbens in zwei. getrennte Teile keine Schwierigkeit, bedeutet aber eine Verteuerung der Herstellung und ,dies Zusammenbaues.All known. However, spring arrangements are not sufficient, to withstand the high hydraulic working pressures in the long term. The least Fatigue phenomena in the springs are sufficient for knocking noises to occur allow. The accommodation of sufficiently strong feathers is generally only one Question of space. It offers the division of the double piston into two. separate parts no difficulty, but it means an increase in the cost of manufacture and assembly.

Die Erfindung bezieht sich auf einen Stoßdämpfer mit einem einteiligen Doppelkolben und besteht darin, daß ein Teil dies Druckgehänges selbst als Feder ausgebildet ist, indem der Steuernocken mit einer radialen Schlitzung versehen und mit Vorspannung zwischen die nicht abgefederten Angriffsflächen des Doppelkolbens eingesetzt wird.The invention relates to a shock absorber with a one-piece Double piston and consists in the fact that a part of this pressure hanger itself as a spring is formed in that the control cam is provided with a radial slot and with preload between the non-sprung contact surfaces of the double piston is used.

Der durch die Erfindung erzielte wesentliche Fortschritt besteht nicht allen Inder vergrößerton Billigkeit in Herstellung und Zusammenbau, sondern in der Hauptsache in der kräftigen Federwirkung des geschlitzten Kolbens. Um das seitliche Spiel unmöglich zu machen, wird die Auesparung des Kolbens für den Eintritt des Steuernockens beiderseits in bekannter Weise mit Führungswangen versehen.The substantial progress achieved by the invention does not exist all Indians increase tone of cheapness in manufacture and assembly, but in that The main thing is the powerful spring action of the slotted piston. To the side To make play impossible, the recess of the piston for the entry of the Control cam provided with guide cheeks on both sides in a known manner.

In ..der Zeichnung ist ein Ausführungsbeispiel des Flüssigkeitsstoßdämpfers nach der Erfindung dargestellt.In .. the drawing is an embodiment of the liquid shock absorber shown according to the invention.

Abb. i i!st eise Längsschnitt durch den Flüssigkeitsstoßdämpfer, Abb.2 ein Querschnitt: Abb. 3 gibt einen Schnitt nach der Linie C-C der Abb. i wieder.Fig. 1 is a longitudinal section through the liquid shock absorber, Fig. 2 a cross-section: Fig. 3 shows a section along the line C-C of Fig. i.

. i ist das Gehäuse des Flüssigkeitsstoßdämpfers, das in seinem oberen Teil einen Flüssigkeitsbehälter 2, in seinem unteren Teil die Zylinder 3 und 4 für einen ungeteilten Doppelkolben 5 einschließt. Die Enden der Zylinder sind durch Überwurfmuttern 6 abgeschlossen und abgedichtet.. i is the housing of the liquid shock absorber, which is in its upper Part of a liquid container 2, in its lower part the cylinders 3 and 4 for an undivided double piston 5 includes. The ends of the cylinders are through Union nuts 6 completed and sealed.

In dem oberen Teil ist die Nockenwelle 7 gelagert, die durch den Hebel 8 in Schwingungen versetzt wird: Auf der Welle 7 sitzt der Steuernocken 9, der durch einen radialen Schlitz io federnd gestaltet ist. Dieser Steuernocken ist mit Vorspannung in die Aussparuing i i des Doppelkolbens 5 eingesetzt und liegt unmittelbar auf dein Rückenflächen 12 des Doppelkolbens 5 an. Die Aussparung für den Kolben hat auf beiden Seiten Führungswangen 13, so daß jedes seitliche Spiel des Kolbens verhindert ist.In the upper part the camshaft 7 is supported, which is controlled by the lever 8 is set in vibration: The control cam 9 sits on the shaft 7 and passes through a radial slot io is designed to be resilient. This control cam is pretensioned inserted into the recess i i of the double piston 5 and lies directly on the back surfaces 12 of the double piston 5. Has the recess for the piston guide cheeks 13 on both sides, so that any lateral play of the piston is prevented is.

In dem Kopf des Kolbens sind Nachfül.lventille-14 angeordnet, deren Kammern 15 durch Kanäle 16 mit dem Flüssigkeitsraum 2 in Verbindung stehen.Refill valve 14 are arranged in the head of the piston Chambers 15 are in communication with the liquid space 2 through channels 16.

Die Zylinder 3 und 4 stehen durch ventilgesteuerte Kanäle 17 und 18 miteinander in Verbindung. Die Steuerventile sind mit i9 und 2o bezeichnet. Diese Einrichtung ist an sich bekannt. Die Strömung der Flüssigkeit aus dem Zylinder 3 in den Zylinder 4 und umgekehrt ist durch Pfeile angedeutet (Abb. 3).The cylinders 3 and 4 stand through valve-controlled channels 17 and 18 in connection with each other. The control valves are labeled i9 and 2o. These Facility is known per se. The flow of liquid out of the cylinder 3 in the cylinder 4 and vice versa is indicated by arrows (Fig. 3).
